Advice on cucumbers please

oh, this happened to me when I grew my first cucumber (Telegraph Improved) many years ago.  I'm sure someone advised me to nip off some of the fruits so that all the energy could go into one of them to develop properly - a bit like, the more you crop eg courgettes, the more they produce flowers and fruits scenario.

Before you take the surplus off, I would feel a bit happier if someone else could confirm this!!   I've always grown Marketmore and Crystal Lemon since then and never had the same problem so I can't be sure if what I did was right or wrong.

My outdoor cuc's...(marketmore)...are really struggling,something keeps munching them at ground level,I arrive at the plot to find another toppled over and wilted.I'm certain it's not slugs....keep replacing them but currently there are only two left .....none of the other squashes/courgettes in the same bed are affected.....beginning to think cuc's are going to be off the menu this summer

This year I'm doing an experiment with my outdoor cucumbers. I've got 4 plants in 2 growbags, 2 directly into the bags and 2 in bottomless pots sitting on top of the bag. We're not far into the season and none have started fruiting yet, but even now the 2 in pots look way stronger and healthier than the 2 directly into the growbags. In fact, one of the latter looks like it's dying. I haven't fed them with anything and haven't done an awful lot of watering because we've had quite a lot of rain since they went out, but when I did water both bags were watered into a separate hole in the bag.

If your weather is somewhat cool, cukes just won't grow until the weather warms up as they're decidedly a hot weather crop. That could be a big part of the problem - they're just in a holding pattern waiting for better weather.
